FASTENING-INSERTING MACHINE.

Application filed October 19, 1917.

To all whom it may concern:

Be it known that I, FRED L. MAoKnNzin, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in F astening- Inserting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastening inserting machines, and is herein illustrated as embodied in a machine for inserting previously formed fastenings into shoe stock of the type shown in the patent to Godd-u, No. 1,030,775, granted June 25, 1912, to whlch patent reference may be made for a complete disclosure of various parts not fully described herein.

The fastening inserting mechanism of machines of this type comprises a driver for forcing the fastenings into the stock, a fastening receiving member having a passage formed therein to receive the driver, and a raceway for supplying fastenings to the fastening inserting mechanism. The delivery end of the raceway is spaced from the fastening receiving member a sufficient distance to permit means, commonly denominated a separator, to pass between them. The separator operates to select the fastenings one by one from the raceway and move them to the passage in the fastening receiving member. A part is integrally formed on the delivery end of the raceway for conveying the fastenings across the space between the delivery end of the raceway and the fastening receiving member to the passage in the fastening receiving member.

- Although such construction has proved to be in the main satisfactory there are some disadvantages attendant to its use. It is desirable that the upper or fastening supportin surface of the part on the delivery end 0 the raceway be located as close as possible to the top of the separator which passes beneath it in order that the separator may be caused to engage the fastenings as near to the heads thereof as possible to enable the separator to move bodily into the Specification of Letters Patent.

passage of the fastening receiving member without pivotal movement about their heads, such as results if the separator engages the fastenings too near their pointed ends. For

this reason it is necessary to aline the raceway carefully with the fastening receiving member, and to that end the delivery end of the raceway and the part formed thereon are carefully finished and ground afterbeing cast. If the delivery end of the raceway or the part formed thereon is inaccurately rounkl so as not to properly eoact with the fastening re ceiving member or with the separator, the entire raceway must be scrapped. In machines in which the raceway is formed to provide a plurality of sources of fastening supply, the raceway and the fastening receiving member are shiftable relatively to each other so as to bring either of the sources of fastening supply of the raceway into operativ'e relation with the passage of thememher. The raceways of such machines must be retaining important advantages of known constructions, will be free from the abovementioned and other disadvantages.

An important feature of the invention consists in providing the fastening receiving member of the fastening inserting mechanism, with a part extending in the direction of and to a point adjacent to the plane end surface of the raceway, the raceway being formed to present a su stantially horizontal fastening supporting surface at its end and said part operating to guide and convey the fastenings from the end of the raceway to the passage of the fastening receiving member. In accordance with a further feature of the invention, a guiding member is provided independent of the above-mentioned part for guiding the fastenings in their passage from the raceway to the fastening receiving member.

Said guiding member is preferably p tion willloe=apparent as the description prospaced from the above-mentioned part a sufi'icient distance to receive the separator between them.

When mechanism constructed in accordance with thepresent invention is used, the raceway can be initially cast in a form requiring very little finishing to prepare it for use on the fastening insertingm-achine, and can thus be manufactured easily and cheaply, Whereas the raceway as hereto-fore constructed required a considerable amount of grinding and finishing rafter. the casting was formed, making its manufacture relatively diflicult ria'nd costly. Moreover, if in the use of the-present construction, the part which guides and conveys the fastenings from the delivery end of the raceway to the {fastening inserting mechanism is rendered unfit -for use, :thus necessitating the 'substitutiomio'f a?-'I1eW pLI-t, the expense in- :vol-vediis much. less than that entailed by the substitution of a: new raceway.

:Inracc'ordance with a further feature of the I invention, la raceway formed 7 to provide -aiplurality of: sources of fastening supply is :pivotediat aipoint removed fr'omi-thefastening receiving mem'berand has its end-surfaces-formed atransacute :angle to its center line on axis on ieac'hsi'de o'f the axis to permit the end surface'ofthe raceway at either side of the :axis to he (brought into. a position Lparallel to an'd inelose engagement with the end: of the part whicheguides the fastenings fromeither 'ofzthe sources of fastening sup- :ply of 1 the raceway to the fastening .1 receiving memb er. 7 V Althoughthe' invention is illustrated: :and described 'asembodie d 1 in the type of fastening "inserting machine shown in a: the :patent to Goddu No. 1,030,775,=iit:.is recognized that the 5 invention, or various features; thereof,

The raceway 6 1s preferably .formedjto provide a plurality of: sources of ifastening supply. As shown in Figs. :1 and ,2, two

sources of fastening supply are provided comprising, Efastening receiving slots diverging from I the delivervend of the raceway toward its upper endYwhich passes into: the receptacle 4, said receptacle embodying :two rotatable hoppers 10 31111512 provided with vanes 14 which raise the fastenings asithe 'hoppersgare rotated and deliver them .upon shelves 16 extending fromtheend-ofthe' raceway, as shown clearlylin Figs. l. and-2 of;the drawings- The hoppersiare rotated by .gearing 18' :in the usual manner -..-and

shields-20 are provided in-each ofv the hop- :pers to overlie the slotsin the'raoeway and remove-any fastenings whicl1 -'are:not;properly positioned inzthe slots oftheraceway.

The construction thus far described is illus- 1 trated and described in: the patent-to Mackenzie, No. 1,225,837 grantedlMayi 15, 1917, and forms no part of the present invention,

for which reason a;more,completezelescriptionwof the sameis deemedwunnecessary.

Referring partlcularly toiFigs. :1. and .2.- of

the drawings,.there is provided a.fastening' recelv ng-meinber *8 Which. hasa, passage; 24;

to receive. the fastenings and -whi ch also acts tenings into the work. As illustrated, -the end surface F28 ofv the raceway tie a plane endsurface. In other words, the raceway has allportions of its endsurfacesubstantially in the same plane and the cover .plate 22 of eachofthe slotsof the raceway-extends beyond the end of the raceway and overlies a. portion. of. the-:upper lug or projection 30 r of the driver guide which: extends" beyond the-fastening receiving passage-,2i, ;of the.

driver guide in the direction of% the-*end of the raceway. The lug 30 is iormed with :a

as @a guide for a driver :26 .to insert the "fas slot 32 which is adapted to be alined with the slot or slots of the raceway to receive the fastenings from the slot of the raceway and to guide and convey the same to the passage of the driver guide. The portion of cover plate 22 which extends beyond the end of the raceway and over the slot of the lug 30 to a point adjacent the passage of the driver guide assists in guiding the fastenings from the end of the raceway to the passage of the driver guide. Means are provided for moving the fastenings one by one along the slot of the lug 30 to the passage of the driver guide in the form of a separator 34 havin a part 36 which moves in a passage defined on one side by the wall of the driver guide, on the other side by the end wall 28 of the raceway, at the top by the lug 30, and at the bottom by a second lug 38 formed on the driver guide. The 111 38 prevents the pointed ends of the fastenings from being moved laterally by the separator and assists in guiding the fastenings to the assage 24.

The raceway is mov. le by connections with a rod 40 from the position shown in Fig. 2 to and from the position shown in Fig. 3. The rod 40 may be operated in any suitable manner, (not shown), the operating means therefor forming no part of the present invention.

Referring to Figs. 2 and 3 of the drawings, it will be seen that the end surfaces of the raceway on each side of its axis as indicated at 42 and 44 are formed at an angle to the center line or axis of the race-- way slightly less than a right angle to permit pivotal movement of the raceway on its fulcrum 46 so that either of the slots of the raceway may be alined with the slot 32 in the lug 30 of the driver guide. The degree of the angle is so related to the distance from the delivery end of the raceway to its fulcrum 46 as to permit the lugs on the driver guide to be brought into close association with either of the end surfaces of the raceway as is essential to the proper transfer of the fastenings from the racewaiy to the lug 30 of the driver guide.

11 Fig. 2 of the drawing the outer slot is shown in operative relation to the passage of the driver guide, the fastenings in the inner slot being retained by engagement with the lug 30 on the driver guide and with the separator. Fig. 3 shows the inner slot of the raceway in operative relation to the passage of the driver guide, the fastenings in the outer slot being retained by engagement with the lug on the driver 'uide. am enabled to utilize the lug on tiie driver guide as a retainer for the fastenings in the outer slot by extending it beyond the separator in the direction of the end of the raceway whereby it restrains the fastenings in said slot from movement into the path of movement of the separator.

The parts shown in Fig. 4 are arranged similarly to the parts described, it being noted, however, that in said figure is illustrated an embodiment of the invention comprising a raceway 106 having a single slot only which alines with the slot 132 of the upper lug 130 of the driver guide 108. The separator 134 operates in the manner previously described to move the fastenings one by one along the lug 130 to the passage 124 of the driver guide 108.

In Figs. 5 and 6 is shown a modification of the driver guide applicable to use with either the double raceway illustrated in Figs. 1, 2 and 3, or with the single raceway as illustrated in Fig. 4. In the modification, the upper lug instead of being integrally connected to the driver guide as in the constructions illustrated in Figs. 1, 2, 3 and 4, is in the form of a plate 230 detachably connected thereto by means of screws 48 and 50. With reference to Fig. 6, it will be noted that the plate 230 constituting the upper lug has a widened portion 53 provided with an opening 52 to receive the screw 48 and a slot 232 to receive a fastening from the slot or slots in the raceway, and a reduced portion 54 forming a shoulder 56 which abuts against the end wall 58 of a groove formed in the driver guide at right angles to the fastening receiving passage. The slot 232 of the plate 230 is enlarged at 233 to form an opening alining with the passage 224 of the driver guide. The screw 50 is formed with a head which abuts against the edge of the reduced portion 54 of the plate 230, thus se-- curing the same firmly in position. If the detachable plate 230 on the driver guide becomes bent or broken, it can be replaced with little trouble or expense.

Fig. 7 illustrates a still further modification of the invention, involving differences in the construction both of the raceway and driver guide from the devices previously described. The upper surface of the raceway 306 is recessed at the delivery end oi. the raceway as indicated at 60, and the driver guide 308 is provided with the upper lug 330 and lower lug 338 extending therefrom in the direction of the end of the race way. As illustrated the upper lug 330, which is in the form of a plate detachably connected to the driver guide in the manner shown in Figs. 5 and 6, is extended to lie in the recess 00 in the end of the raceway. In this construction, the upper lug 330, the upper surface of which lies in the same plane with the upper surface of the raceway to the rear of the recess (30, receives the fastenings before they have left the raceway.

A still further modification of the invention is illustrated in Fig. 8, which constrnction embodies a driver guide 408 having a lug 430 extending therefrom in the direction of the raceway as in the constructions previously described. In this construction, however, the lower lu-g 438 which, in connection with the upper lug, forms a passage-way through which passes the upper section 436 of the separator, is provided at the end of the raceway 406 rather than on the driver guide, as in the constructions previously described.
